docs: update multi-node workflow with pre-flight setup

- Add comprehensive pre-flight setup section covering all required steps
- Include systemd service updates, CLI setup, and config relocation
- Update aitbc1 and aitbc setup sections to reflect pre-flight completion
- Remove redundant steps from main workflow (moved to pre-flight)
- Add verification commands to ensure setup is correct
- Streamline workflow execution by handling prerequisites upfront

This makes the workflow more robust and ensures all prerequisites
are met before starting the actual blockchain deployment.

+## Pre-Flight Setup
+
+Before running the workflow, ensure the following setup is complete:
+
+```bash
+# 1. Stop existing services
+systemctl stop aitbc-blockchain-* 2>/dev/null || true
+
+# 2. Update systemd services to use standard config location
+sed -i 's|EnvironmentFile=/opt/aitbc/.env|EnvironmentFile=/etc/aitbc/blockchain.env|g' /opt/aitbc/systemd/aitbc-blockchain-*.service
+systemctl daemon-reload
+
+# 3. Move central config to standard location
+cp /opt/aitbc/.env /etc/aitbc/blockchain.env.backup
+mv /opt/aitbc/.env /etc/aitbc/blockchain.env
+
+# 4. Setup AITBC CLI tool
+python3 -m venv /opt/aitbc/cli/venv
+source /opt/aitbc/cli/venv/bin/activate
+pip install -e /opt/aitbc/cli/
+echo 'alias aitbc="source /opt/aitbc/cli/venv/bin/activate && aitbc"' >> ~/.bashrc
+source ~/.bashrc
+
+# 5. Clean old data (optional but recommended)
+rm -rf /var/lib/aitbc/data/ait-mainnet/*
+rm -rf /var/lib/aitbc/keystore/*
+
+# 6. Verify setup
+aitbc --help
+ls -la /etc/aitbc/blockchain.env
+```
